SAMUEL A. LIVINGSTON, OF EAST NEW YORK, N. Y.

AIR COMPRESSOR AND FAUCET.

SPECIFICATION forming part of Letters Patent No. 242,008, dated May 24, 1881.

Application filed February 18, 1881. (ModeL) To all whom it may concern Be it known that I, SAMUEL A. LIVINGSTON, of East New York, in the county of Kings and State of New York, have invented a new and Improved Air 0on1 pressorand Faucet, of which the following is a specification.

The object of my invention is to aerate beer, as well as create a pressure by forcing air up through the liquid; also, to allow a keg to be tapped without permitting the natural gases of the liquid to escape, and without the use of bungs or other vents. By my device this can be done when under pressure due to effervescence.

In the accompanying drawings, Figure l is a longitudinal section of my device. Fig. 2 is a side elevation of the same, and Fig. 3 is a cross-section on line a w of Fig. 1.

Similar letters of reference indicate corresponding parts.

A is a tubular plug constituting the barrel of the air-pump, and formed with its end a tapered, for being driven tightly into the bunghole of a barrel or keg.

B is a rod carrying within the barrel ahead, I), that is suitably packed and c is a cap fitted on the outer end of barrel A, through which cap the rod B works.

at is a perforated nipple attached on barrel A, near theinner end, over an aperture in the barrel, and containing a ball-valve, e, that works between a cage fitted over the opening and the aperture in the nipple d.

f is a ball-valve fitted in barrel A, beyond the reach of piston B, and between a slat, f, and a cross-bar, 9, that prevents the valve being forced intothe barrel.

h is a faucet formed with or attached upon the barrel A, near the outer end thereof. From this faucet a tube or passage, 6, extends along the side of barrel A, to near its inner end, such passage opening into the aperture of the barrel beyond the valvef, so that when the plug of the faucet is turned to coincide with the passage 43 the beer or other liquid may run out.

In use the plug or barrel A will be driven into the bung-hole of the keg, and the liquid can-then be drawn through faucet h. When the keg is partially emptied the faucet is to be closed and piston B worked to draw air in through nipple cl, and force the same into the keg until the desired pressure is obtained. This compressed air has the effect to aerate the liquid, and gives the pressure required to force the beer out of faucet h when the latter is again opened. The valve fprevents the liquid from passing into the barrel A.

The piston B is provided with aknob, 7.", for convenience in operating it, and on this knob is a headed pin or flanged lug, 1, adapted for entering a slot, m, in cap 0. The slot at is the segment of a circle and diminishes in size from one end, so that when the piston is pushed inward and given a quarter-turn the head of pin l will take between the edges of the slot, and thus prevent the piston from being forced out.

Other devices may be used in place of pin land slot on for the same purpose, and I do not commit myself to ball-valves, as any suitable valves may be used.

The nipple d is shown as formed with a screw-thread for connection of a pipe. This is used when liquid is to be forced into the keg or barrel instead of air, so that the liquids can be thus mixed and then drawn together.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In an air compressor and faucet, the tube A, having the tapered drive end a, the valved perforated nipple cl, the valve f in said tube, and the faucet it, connected by passage i with the inside of tube, in combination with the rod B, having a head, I), and working through a cap, 0, for the purpose specified.

2. Cap 0, having slot m, and piston B, provided with pin Z, combined for operation substantially as and for the purposes specified.

SAMUEL A. LIVINGSTON.
